摘要：

【目的】利用微卫星标记技术对来自新疆和宁夏的48株酿酒酵母菌株进行区分,并分析其亲缘关系。【方法】选择4个微卫星位点:SCAAT1、SCYOR267c、C11和YPL009c,用其多态性对48个菌株进行分析。【结果】4个微卫星标记在48株菌中共检测到87个等位基因,39种基因型;4个位点多态信息含量为0.8593—0.9115,均为高度多态位点;期望杂合度(heterozygosity expected,He)和观测杂合度(heterozygosity observed,Ho)分别为0.8803—0.9268和0.8333—0.9792。【结论】宁夏和新疆地区酿酒酵母菌株生物多样性丰富。
